Re: Blind Spot Monitoring/Adaptive Cruise Ctl

My $.02:

I was not going to buy with the ACC package but the only available vehicle that met my needs had this package already, so I opted for it.

I lucked out, it really is as good as people are saying. I live near Boston, and this area has some of the worst driving habits in the US. These are challenging conditions for an automated system.

I find that the gaps present safe distances, but people will always cut in front of you around here. It does get annoying that the ACC brakes pretty hard to maintain that gap and you feel like a jerK hitting your brakes when you really didn't have to as someone cuts in front.

However, if you can get into traffic that can at least maintain about 20 mph then it's a huge relief. You set it and just let it manage the speeding up / slowing down garbage that plagues this area. My commutes generally go below the 15 mph min too often, but if can help ease my driving for even 30% of the my commute it's awesome.

It does read a vehicle accelerating away from you when you pull out behind someone to pass and is smart enough not to hit the brakes, then immediately speed up. Nice feature.

My collision warning has gone off about 4 times already in 2 weeks, but each time it was completely warranted. Around here people just ride someone's tail at 60 mph and then slam on their brakes. The radar definitely figures out that your distance and rate of closure is a problem and chimes. It has done this while I was looking right at the traffic, and also while fiddling with the radio. It's very helpful, and does it at the appropriate time.

I'm very happy I got this feature, and on the few occasions when I have not been dealing with Boston traffic, it is that much sweeter. You just set it and run....

I'm starting to really enjoy some of these new safety and convenience features. I would not hestiate to buy it again.

-Ryan

And, because I'm sure someone is going to ask -- NO, the ACC won't bring you to a complete stop.

I tested this by turning it on in a 30 MPH zone and following a guy up to a stop sign with my foot hovering over the brake. At 15 MPH the ACC chimes "speed too slow" and turns itself off.

Get the ACC!
The more I use it the more I love it.

I'm getting so comfortable with it now that when I'm exiting an interstate driving 75mph I let the ACC follow the car infront until the last few feet before I need to stop. It's soooo cooool.

Also those annoying drives home on county roads where there is no hope in passing the line of cars... just turn on the ACC and never hit the brakes for miles and miles even when people are slowing down to pull into their driveway, or when the speed drops from 55 to 30.

I love ACC!

Re: Blind Spot Monitoring/Adaptive Cruise Ctl

Has anyone noticed that the ACC system will accelerate some if you turn on your left turn signal when you are going to pull out and pass a car going slower than your set speed? This is another nice feature.

I think it's doing that independent of the turn signal (you're probably just a courteous driver who always uses a signal so it seems that way).

The ACC is detecting a clear path ahead as soon as you enter enough deflection in your path of travel so that it can no longer "see" the car you're going around. It's the same as if a slow car in front of you switched lanes and got out of your way...the ACC would kick it up to your preset speed.

ACC is sexy, dudes.

I think it will accelerate some when you turn on the left turn signal before the car in front is out of the way. Give it a try.

I will give it a try and I pray that it does not work that way. I would consider it a malfunction for an intentional or accidental trip of the turn signal to cause my vehicle to accelerate. Too many scenarios where that would not be cool (even if there are some where it would be desirable and expected behavior). For instance, I often put my blinker on to signal my intentions way before it is safe to change lanes or turn. Thanks for the heads up, imeh. I'll report back with findings.

I think you are correct. I have noticed that too. To me is seems like a nice feature and works well for the way I drive.

If you haven't noticed it yet, then I don't think it will interfere with the way you drive. It is somewhat subtle and will not do anything bad if you turn on your signal and don't change lanes.

Re: Blind Spot Monitoring/Adaptive Cruise Ctl

I noticed a correlation, but I hadn't done enough testing to decide if it's causation, or if, as I start to move left the ACC is no longer painting the vehicle in front of me and beginning to resume it's set speed.

And yes, I use the turn signal EVERY time. Hell, I use a turn signal if I'm the only car on the road. After 20 years of driving it's just habit.

Re: Blind Spot Monitoring/Adaptive Cruise Ctl

That's my theory also, B-- correlation and not causation. Should be easy enough to test with or without blinkers. If your WK2 accelerates as reported, depress the brake, disable ACC, and drive directly to your closest Jeep service department.

This "feature" would make no sense from a design or safety perspective. While it might seem like a "cool" feature that anticipates your next move, driving is far too dynamic for something like this to be included as a convenience feature.

Thanks for the extra info; glad to hear that it is not happening unless you change lanes, which suggests it is a function of the radar's spread and not the turn signal.

I am not the type of lane changer who just drifts over. Maybe that's why I never noticed it, since I'm goosing it anyway.
